Wearable technologies impact on human performance monitoring. Technology designed for human monitoring was used as a proof of concept study to determine the effectiveness of monitoring physical activity of two different sized dogs. The device found significant step count differences with the smaller dog having greater step count. This was confirmed from step counts taken from an associated video recording. Therefore the study showed that a wearable device could measure step counts of dogs. Meaning that users can monitor their own physical activity or that of their pet with the same device.
